what did the cannibals wanted to eat

The cannibals preferred food is human bodies.

Besides, after some thought upon this affair, I considered that if this land was the Spanish coast, I should certainly, one time or other, see some vessel pass or repass one way or other; but if not, then it was the savage coast between the Spanish country and Brazils, where are found the worst of savages; for they are cannibals or men-eaters, and fail not to murder and devour all the human bodies that fall into their hands.
